Kernpunkte

The general trend is for gradually rising freezing levels and clearing skies. In the meantime pay attention to the bond of the recent new snow to the old snow surface.

    When the sun comes out it will quickly weaken the new snow and cause loose wet avalanching on steep solar slopes.

Confidence

Low - Due to the number of field observations

Avalanche Summary

Several loose wet avalanches up to size 2.5 which were triggered by cornice falls were reported near Fernie on Sunday.

Snowpack Summary

15-25 cm of new snow and moderate winds have formed storm slabs reactive to human triggers. This storm snow overlies numerous crusts in the upper 100 cm of the snowpack.The mid-pack is generally well settled and strong.A layer of sugary facets around a crust can be found near the bottom of the snowpack which has been dormant for some time. Large triggers, such as a falling cornice, or a major warm-up to the snowpack could trigger this layer.
